Pharmacokinetics and brain σ1 receptor occupancy of MR309, a selective σ1 receptor antagonist.

Aims: Preclinical studies of MR309, a selective sigma-1 receptor (σ1R) antagonist, support a potential role in treating neuropathic pain. We report 2 studies that provide insight into the pharmacokinetics (PK) and brain σ1R binding of MR309.

Methods: Steady-state PK of MR309 (400 mg once daily and 200 mg twice-daily [BID] for 10 days; EudraCT 2015-001818-99 [PK study]) and the relationship between MR309 plasma exposure and brain σ1R occupancy (EudraCT 2017-000670-11 [positron emission tomography study]) were investigated in healthy volunteers.

Non-interventional study of the safety and effectiveness of fluticasone propionate/formoterol fumarate in real-world asthma management.

Introduction: In recognition of the value of long-term real-world data, a postauthorization safety study of the inhaled corticosteroid (ICS) fluticasone propionate and long-acting β-agonist (LABA) formoterol fumarate (fluticasone/formoterol; Flutiform) was conducted.

Methods: This was a 12-month observational study of outpatients with asthma aged ⩾ 12 years in eight European countries. Patients were prescribed fluticasone/formoterol according to the licensed indication, and independently of their subsequent enrolment in the study.

Pharmacokinetics of Tramadol and Celecoxib in Japanese and Caucasian Subjects Following Administration of Co-Crystal of Tramadol-Celecoxib (CTC): A Randomised, Open-Label Study.

Background And Objectives: Co-Crystal of Tramadol-Celecoxib (CTC) is a first-in-class active pharmaceutical ingredient (API-API) co-crystal of rac-tramadol.HCl and celecoxib in a 1:1 molecular ratio (100 mg CTC: 44 mg rac-tramadol.HCl and 56 mg celecoxib).

Pediatric oncology clinical trial participation where the geography is vast: Development of a clinical research system for tertiary and satellite centers in Ontario, Canada.

Opportunities for participation in clinical trials are a core component of the care of children with cancer. In Ontario, many pediatric patients live long distances from their cancer center. This paper describes the work that was done in order to allow patients participating in Children's Oncology Group trials to receive care, including research protocol related care, jointly between the tertiary pediatric cancer center and the closer-to-home satellite center.
